[horde] Customizing Horde Menu

[Elliot Anders]

I'm trying to add some links to the Sidebar menu in Horde using  
registry.php.
I've been following this example: http://wiki.horde.org/CustomizeMenu  
and have come up with the following, which works, but also adds links  
to the "Options" menu (bug?).  As I'm just trying to link to offsite  
services this makes no sense.  Is there a way to exclude that  
automatic inclusion?
I'm using Horde Webmail 1.1

// Custom Menus
$this->applications['mc_custom'] = array(
        'name' => _('External Links'),
        'status' => 'heading',
        'icon' => ''
);
$this->applications['mc_courses'] = array(
    'webroot' => 'https://www.example.com,
    'name' => _("Example Link"),
    'status' => 'active',
    'target' => '_parent',
    'menu_parent' => 'mc_custom',
    'icon' => ''
);

Thanks,
Elliot
